SIO Abalone OBS

SIO operates 15 of the Abalone-style OBS. The Abalone instruments were built for the Cascadia Intitiative. The “standard package” is robust enough to offer a suite of sensor options while maintaining trawl resistance, seismometer isolation and current shielding, deep-water capability and robustness through a conformal syntactic-foam flotation- based frame design.
